Police issue a new appeal for information as they step up their search to find missing toddler William Tyrell before Christmas.
It has been two months since the three-year-old vanished without a trace from his grandmother's home on the NSW Mid North Coast on September 12.
While hundreds of pieces of information have come through Crime Stoppers at this stage investigators say there are no new leads.
"There's a challenge out there and the challenge is to ensure that especially with Christmas coming up that we are able to locate young William and be able to provide the family with some sort of outcome," Superintendent Paul Fehon of the NSW Police told 7 News.
Of William's family Supt. Fehon said: "You can understand their despair and pain."
But police are optimistic and believe by lodging a new public appeal someone who knows something will come forward.
"Without locating him in the bush, we are still hopeful of being able to locate young William," Supt. Fehon told the Sydney Morning Herald.
The notion that William had some kind of misadventure on his own on the day of his disappearance seems to be unlikely as police, SES volunteers, RFS volunteers and community members spent 11 days searching areas spanning 48 kilometres and turned up with nothing.
"We are completely open to any possibility, including human intervention," Supt. Fehon said.
"If that has occurred, somebody knows something."
Anyone with any information is urged to contact Crime Stoppers on 1800 333 000.
When was William last seen?
William disappeared from his grandmother's home in Benaroon Drive, Kendall, on the NSW Mid North Coast at 10:30am on September 12.
Police believe the toddler disappeared in a five-minute window while playing alongside his sister in his grandmother's yard.
What does he look like?
William has been described as being of Caucasian appearance with dark hair and hazel eyes. He was last seen wearing a Spider Man suit.
What is being done to find him?
Police, SES volunteers and members of the public have searched an area of more than 50sq kilometres including bushland and waterways.
Strike Force Rosann has been formed to investigate the disappearance and investigators have engaged in a door-to-door campaign of the Kendall community to gather information.
What have police found?
So far investigators have failed to find any trace of William but they hope a new public appeal will lead them to find the toddler before Christmas.
Was he abducted?
Police are treating the investigation as a search for a missing child, but have not ruled out the possibility of abduction.
Police have reportedly spoken with all known sex offenders in the region.
Police are urging anyone with information about this incident to call Crime Stoppers on 1800 333 000 or use the Crime Stoppers online reporting page.
